A US satellite company has said it has taken photographs of sea trials taking place for China's first aircraft carrier.
The as-yet unnamed carrier is the former Soviet Varyag which was bought from Ukraine in 1998.
It has undergone years of refurbishment after it was sold without engines, weaponry and navigation systems.
The images, captured by
Digitalglobe, are believed to have been the first time the 300ft ship has been photographed since it was first dispatched for trials in August.
The trials, which have been kept relatively low-key, have drawn considerable attention from around the world as China has not previously been regarded as an international military power.
Japan has been keeping an especially close eye on the carrier's movements as defence experts are wary of the Chinese navy's increasing presence in Japanese waters.
China has said the carrier is intended for research and training, leading to speculation that it plans to build future copies.
A statement issued by the Defence Ministry in November said the exercises were not directed toward "any particular country or objective".
While no major problems have been reported in making the 55,000-ton ski jump-style carrier seaworthy, Beijing is believed to be years away from being able to launch and recover aircraft from it as part of a carrier battle group.
